Description
Technical Field
[0001] The present invention relates to the technical field of electric energy meters, in particular to an electric energy meter capable of remote meter reading. Background Art
[0002] In the field of electricity metering, traditional electricity meters mainly use mechanical or electronic metering methods and rely on manual regular meter reading, which has problems such as low efficiency, high cost and easy errors. With the development of smart grids, some electricity meters have local communication functions, but staff still need to collect data on site, which cannot meet the needs of real-time monitoring. Existing remote meter reading technologies mostly use GPRS wireless communication solutions, but the communication stability is insufficient in complex electromagnetic environments, and the high power consumption design affects battery life. In addition, the structural design of traditional electricity meters does not fully consider dust and water resistance and anti-interference capabilities. Data loss or measurement deviation is prone to occur under harsh working conditions. At the same time, there is a lack of a unified data security mechanism, and there is a risk of information leakage. These technical bottlenecks restrict the reliability and large-scale promotion and application of smart electricity meters.
[0003] Existing electricity meters in the existing technology have obvious defects in mechanical structure and maintenance convenience: First, the traditional cover is fixed with screws or ultrasonic welding technology, and after long-term use, the sealing performance is easily deteriorated due to material aging or mechanical stress, which significantly increases the risk of dust intrusion and water ingress; second, the structural design lacks a modular concept. When the communication module needs to be removed, multiple sets of fixing screws need to be removed, which not only greatly increases the complexity of the maintenance operation. Summary of the Invention
[0004] Based on this, the purpose of the present invention is to provide an electric energy meter that can be remotely read, so as to solve the technical problems that the cover fixing method of the traditional electric energy meter is prone to reduced sealing due to material aging or external force, increasing the risk of dust and water ingress, and when the modular design is insufficient, the replacement of parts requires the entire meter to be disassembled, increasing operation and maintenance costs.
[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an electric energy meter capable of remote meter reading, comprising a protective shell, an electric energy display meter being arranged inside the protective shell, a clamping mechanism being arranged inside the protective shell, a communication module being arranged inside the protective shell, and the communication module being coordinated with the clamping mechanism, sealing mechanisms being arranged on all four sides of the protective shell, and multiple groups of electric energy display lights being arranged inside the protective shell.
[0006] By adopting the above technical solution, manually turning the knob causes the worm gear fixed to one end to rotate accordingly. When the worm gear rotates, it also causes the meshing worm gear to rotate slightly. When the worm gear rotates, it also causes the first and second clamping rods located outside of it to move outward, so that the engaging tips at the top of the first and second clamping rods no longer engage the engaging slots within the communication module, thereby releasing the communication module and facilitating replacement and installation of the communication module by external personnel.
[0007] Furthermore, the sealing mechanism includes a rotating bolt, a pressure rod, a movable plate, a spring, a first limiting sleeve, a second limiting sleeve and a blocking block, the rotating bolt is arranged at one end of the pressure rod, the pressure rod is arranged inside the protective shell, the movable plate is arranged on one side of the pressure rod, the spring is arranged on one side of the movable plate, the first limiting sleeve is arranged inside the spring, the second limiting sleeve is arranged inside the first limiting sleeve, the blocking block is arranged at the bottom end of the second limiting sleeve, a through hole is provided inside the first limiting sleeve and matches the second limiting sleeve, a rotating base is provided at one end of the spring, a rotating base fixed to the second limiting sleeve is fixed to the top of the blocking block, and a through hole is provided inside the movable plate and matches the pressure rod.
[0008] By adopting the above technical solution, after installation is complete, the staff manually tightens the knobs to clamp the first and second clamping rods around the communication module, preventing it from falling off during use. The staff then manually twists the rotating bolt, which, through the threads on the outer side of the rotating bolt, forces the rotating bolt to rotate while also moving downward, slowly squeezing the pressure rod, causing it to move parallel downward. As the pressure rod moves parallel, the angles of the movable plates at both ends gradually align with the pressure rod. During this gradual aligning process, the springs at both ends of the movable plates exert a certain amount of spring compression force, thereby ensuring the slow descent of the pressure rod.
[0009] Furthermore, the clamping mechanism includes a knob, a worm, a first clamping rod, a second clamping rod and a worm wheel, the knob is arranged at the bottom end of the communication module, the worm is arranged at the top end of the knob, the first clamping rod is arranged at the bottom end of the communication module, the second clamping rod is arranged on the outside of the worm wheel, the worm wheel is arranged on the outside of the worm, and multiple groups of fixing blocks cooperating with the second clamping rod and the first clamping rod are arranged inside the protective shell, a bearing is arranged between the protective shell and the worm wheel, one end of the second clamping rod and the first clamping rod are both provided with teeth cooperating with the worm wheel, and a cavity cooperating with the second clamping rod and the first clamping rod is opened inside the communication module.
[0010] By adopting the above technical solution, when it is level, the springs arranged at both ends are in the maximum compression state, so as to achieve the maximum extrusion force on the pressure rod and the movable plate, and prevent them from loosening, which causes the blocking block at the contact end of the extruded movable rod and the protective shell to fail to contact the protective shell, thereby affecting the sealing state. A first limiting sleeve and a second limiting sleeve are also provided inside the spring. Because the diameter of the first limiting sleeve is smaller than that of the spring, and the diameter of the second limiting sleeve is smaller than that of the first limiting sleeve, the movement of the first limiting sleeve and the second limiting sleeve ensures that the spring will not be displaced in the fixed position due to pressure.
[0011] To sum up, the present invention mainly has the following beneficial effects: the present invention drives the worm to rotate by manually turning the knob, and the worm drives the turbine to rotate slightly, so that the first clamping rod and the second clamping rod on the outside move outward and disengage from the locking slot of the communication module, and the module can be taken out for replacement. After the installation is completed, the knob is rotated in the opposite direction to clamp the module to prevent it from falling off, and then the rotating bolt is manually tightened to press the pressure rod downward. When the pressure rod moves downward in parallel, the movable plate drives the angle to adjust. At the same time, the compression spring provides a buffering force to ensure that the pressure rod descends smoothly. The first limit sleeve and the second limit sleeve inside the spring limit the displacement of the spring. Finally, the spring reaches the maximum compression state, ensuring that the blocking material fits tightly against the protective shell to achieve sealing. This structure can ensure sealing without screws or ultrasonic welding, reducing the risk of dust and water ingress. There is no need to disassemble the entire module when replacing it, which significantly improves maintenance efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.
[0015] The following describes an embodiment of the present invention based on its overall structure.
[0016] An electric energy meter that can be read remotely, such as Figure 1-7 As shown, the protective shell 1 includes a power display meter 2, a clamping mechanism 4, a communication module 6, and a seal 3 on all four sides of the protective shell 1. The protective shell 1 is provided with a plurality of power display lights 5 ... When the worm gear 405 rotates, it drives the first clamping rod 403 and the second clamping rod 404 provided on the outside thereof to move outward, so that the engaging head ends provided on the top ends of the first clamping rod 403 and the second clamping rod 404 are no longer engaged with the engaging grooves provided inside the communication module 6, thereby releasing the communication module 6, making it convenient for external staff to replace and install the communication module 6. After the installation is completed, the staff manually tightens the knob 401 so that the first clamping rod 403 and the second clamping rod 404 can clamp the communication module 6 to prevent it from falling off during use; Exemplarily, the sealing mechanism 3 includes a rotating bolt 301, a pressure rod 302, a movable plate 303, a spring 304, a first limiting sleeve 305, a second limiting sleeve 306 and a blocking block 307, the rotating bolt 301 is arranged at one end of the pressure rod 302, the pressure rod 302 is arranged inside the protective shell 1, the movable plate 303 is arranged on one side of the pressure rod 302, the spring 304 is arranged on one side of the movable plate 303, the first limiting sleeve 305 is arranged inside the spring 304, the second limiting sleeve 306 is arranged inside the first limiting sleeve 305, the blocking block 307 is arranged at the bottom end of the second limiting sleeve 306, a through hole is opened inside the first limiting sleeve 305 to match the second limiting sleeve 306, a rotating base is provided at one end of the spring 304, a rotating base fixed to the second limiting sleeve 306 is fixed to the top of the blocking block 307, a through hole is opened inside the movable plate 303 to match the pressure rod 302, wherein, By manually twisting the rotating bolt 301 and rotating the threads on the outside of the rotating bolt 301, the rotating bolt 301 is forced to rotate and move downward, thereby slowly squeezing the pressure rod 302, causing the pressure rod 302 to move downward in parallel. As the pressure rod 302 moves in parallel, the angles of the movable plates 303 at both ends gradually become aligned with the pressure rod 302. During this gradual alignment, the springs 304 at both ends of the movable plates 303 exert a certain amount of spring compression force, thereby ensuring the slow descent of the pressure rod 302. Exemplarily, the clamping mechanism 4 includes a knob 401, a worm 402, a first clamping rod 403, a second clamping rod 404 and a worm gear 405, the knob 401 is arranged at the bottom of the communication module 6, the worm 402 is arranged at the top of the knob 401, the first clamping rod 403 is arranged at the bottom of the communication module 6, the second clamping rod 404 is arranged on the outside of the worm gear 405, the worm gear 405 is arranged on the outside of the worm 402, and the protective shell 1 is provided with multiple groups of fixing blocks that cooperate with the second clamping rod 404 and the first clamping rod 403. A bearing is provided between the protective shell 1 and the worm gear 405. One end of the second clamping rod 404 and the first clamping rod 403 are both provided with teeth that cooperate with the worm gear 405. The communication module 6 is provided with a plurality of fixing blocks that cooperate with the second clamping rod 404 and the first clamping rod 403. The cavity that cooperates with the holding rod 403, wherein, when it is level, the springs 304 arranged at both ends thereof are in the maximum compression state, thereby achieving the maximum extrusion force on the pressure rod 302 and the movable plate 303, preventing them from loosening and causing the blocking block 307 at the end of the extruded movable rod 303 in contact with the protective shell 1 to fail to contact the protective shell 1, thereby affecting the sealing state, and a first limiting sleeve 305 and a second limiting sleeve 306 are also provided inside the spring 304. Because the diameter of the first limiting sleeve 305 is smaller than that of the spring 304, and the diameter of the second limiting sleeve 306 is smaller than that of the first limiting sleeve 305, the movement of the first limiting sleeve 305 and the second limiting sleeve 306 can ensure that the spring 304 will not be displaced in the fixed position due to pressure.
[0017] The working principle of the present invention is as follows: During use, a worker installs the entire electric energy meter in the appropriate position and then secures the base plate of the electric energy meter to the wall with screws to prevent loosening. When the communication module 6 installed inside the electric energy meter needs to be replaced, the sealing mechanism 3 is released, thereby loosening the protective shell 1, making it easier for workers to remove the protective shell 1.
[0018] Then, by manually turning the knob 401, the worm 402 fixed at one end of the knob 401 will also rotate. When the worm 402 rotates, it also causes the worm wheel 405, which is meshed with it, to rotate slightly. When the worm wheel 405 rotates, it causes the first clamping rod 403 and the second clamping rod 404 disposed on its outer side to move outward, so that the engaging tips disposed at the top of the first clamping rod 403 and the second clamping rod 404 no longer engage with the engaging slots provided inside the communication module 6, thereby releasing the communication module 6 and facilitating the replacement and installation of the communication module 6 by external personnel.
[0019] After installation is complete, the staff manually tightens the knob 401, allowing the first clamping rod 403 and the second clamping rod 404 to clamp the communication module 6, preventing it from falling off during use. The staff then manually twists the rotating bolt 301, and through the threads provided on the outside of the rotating bolt 301, the rotating bolt 301 is forced to rotate and move downward, thereby slowly squeezing the pressure rod 302, allowing the pressure rod 302 to move downward in parallel. As the pressure rod 302 moves in parallel, the angle of the movable plate 303 provided at both ends gradually becomes equal to that of the pressure rod 302. During this gradual equalization process, the springs 304 provided at both ends of the movable plate 303 will exert a certain spring compression force, thereby ensuring the slow descent of the pressure rod 302.
[0020] When it is level, the springs 304 provided at both ends are in the maximum compression state, thereby achieving the maximum squeezing force on the pressure rod 302 and the movable plate 303, preventing them from loosening and causing the blocking block 307 at the end of the movable rod 303 in contact with the protective shell 1 to fail to contact the protective shell 1, thereby affecting the sealing state.
[0021] Specifically, a first limiting sleeve 305 and a second limiting sleeve 306 are also provided inside the spring 304. Because the diameter of the first limiting sleeve 305 is smaller than that of the spring 304, and the diameter of the second limiting sleeve 306 is smaller than that of the first limiting sleeve 305, the movement of the first limiting sleeve 305 and the second limiting sleeve 306 ensures that the spring 304 will not be displaced from the fixed position due to pressure.
[0022] The above structure eliminates the need for screw fixation or ultrasonic welding processes for the traditional cover of the electricity meter, ensures sealing performance, significantly reduces the risk of dust intrusion and water ingress, and does not require overall disassembly of the equipment when replacing the communication module 6, thereby greatly improving maintenance efficiency.

The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.
